That is absolutely sound advise and we will diffidently keep that in mind as we look for our perfect MFH, but we will definitely open up our prospects and consider SFH as well, maybe with a finished basement with separate entrance or consider renting a room or 2 depending on what we find in our search.

Finish that one garage conversion and stop there.

I have a question about the possibilty of finishing a basement/garage and turning it into a livable space.

If you flip to rent you will go more durable on finishings than you would to sell so you want to decide on that, but when you are done, you can see where you are at for sale vs. rent and decide, you would just have to move to traditional loan to carry it if you rent.

Too good of a deal to pass up even though Lennar is notorious for not giving way on finishes or upgrades. 

About the basement: It's partially finished (drywalls and ceiling only) with no bathroom or kitchen.Since it's a considerably smaller house, I am not sure if this would add significant value to the house if we sell it say 5 years down the line.

To give more content the side I'm currently in I've been renovating ( brand new everything) and once I finish in about 2-3 Months will be for rent for about $400 more than what they are paying now. 

This tenant of yours is not finished pushing the limits of your tolerance.
